Rick,

As Dan had stated bearings and belts (batteries of course) is the key in the North American GT3 & GT2 classes. Because the motors can be under powered in these classes you don't need to worry about the belts skipping.

I generally cook the bearings in an Integy cleaning box for about 4 hours (if new) and run VERY light oil... nearly dry.

The belts can give your a couple of choices. I opt for the low friction hop-up set. I soak them in WD40 for several days to help free them up. Or you can run old belts, they seem to work well also.

When tightening the top deck try to shorten the overall lenght of the upper chassis...if that makes sense. It will provide you with a front belt that is more loose.

Beyond that not much else can be done. I run my GT3 car with one-way diffs and pulleys.

I really wish someone could explain why the 04 series has really tight front belts. This is my 3rd 04 kit (04-Pro,04R,04-TRF) and all were tight as could possibly be. The 414M2 is the exact opposite, nice and loose. Tamiya must know why there making them this way, but doesnt make sense to me.
